Transportation dominates environmental and energy security threats to the world. Light-duty vehicles (LDVs—cars and trucks) accounted for 45.6 % of all the oil consumed by the USA in 2009 and 37.4 % of all greenhouse gas (GHG) emissions. Assuming that economic growth resumes after the 2008–2009 global recession, US vehicle sales and annual miles traveled per vehicle will most likely resume their historical upward trajectories (although probably not as steeply) which will lead to a steady increase in urban air pollution, GHG emissions, and oil consumption, unless we change the way we power our cars, trucks, buses, planes, trains, and ships. Our petroleum consumption and pollution from vehicles in the USA is exacerbated by long travel distances, minimal mass transit, and very low fuel taxes compared to the rest of the world.
